Algebra 1 Chapter 3 Linear Functions

Front

In the equation, y = mx + b, what does the letter b represent?

Back

y-intercept

Front

What is the slope in the equation y = mx + b?

Back

The slope (m) represents the rate of change of y with respect to x.

Front

What is the general form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What does a linear graph look like?

Back

A linear graph is a straight line.

Front

What is the y-intercept of the equation y = 2x + 3?

Back

3

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the slope of the line represented by the equation y = -4x + 2?

Back

-4

Front

If a line has a slope of 0, what does that indicate about the line?

Back

The line is horizontal.

Front

If a line has an undefined slope, what does that indicate about the line?

Back

The line is vertical.

Front

What is the x-intercept of the equation y = 5x - 10?

Back

2 (set y = 0 and solve for x).
